Letters Patent No. 112,006, dated February 21, 1871.

IMPROVEMENT IN CORNfPLANTERS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern: f

, Be it known that I, J AMES M. AITonIsoN, of Omar, in the county of Jeiferson and State oi' New York, have invented a certain new and useful Improvement;

in Planters; and I do hereby declare that the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing forming a part of the same, and in which- Figure l represents a side elevation of my improved planter;

Figure 2 a plan view;

Figure 3 a front; and

Figure 4 a rear view ofthe saine.

This invention appertain's to planters, and consists in the construction and combination -of the constituent parts of the same, substantially as hereinafter set forth and claimed.

Similar letters of the several figures indicate corresponding parts of my invention.

'lo enable those skilled in the art to which my invention appertains to make and use the same, I will proceed to describe `its construction and operation.

In the annexed drawing- A A represents a frame, of ordinary construction, and braced at its center bythe vert-ical bars or pieces c, only one of which is shown in the figure.

c' a designate two transverse bars or braces, one of which is secured to and between the uprights a, ator near ltheir center, and the other to and between the rear supports or legs of the frame A A, in a plane with the former brace. rlhese braces connect the upright's (t together, as do they the rear uprights or supports of the frame A A. i

B B are two rollers, secured upon the rear axle b, jonrnaled in the lower ends of the rear uprights oi' frame A.

Upon one end ofthe axle b fits a pulleyor shipper, B, the axle of which is made hollow, and embraces the axle l), so as to permit of its being slid back and forth thereon,I the object ot which is to throw said pulley in and out of motion,'consequently communieating motion to or cutting it off from its belt when desired.

'lhc hollow axle oi' thc pulley B is constructed with a iange on its projecting end, for the purpose ot' holding the lower bifurcated end of thev handle or shi pper B2 thereon.

lhe inncr side of the pulley B1 is supplied with a series of' projections, b1 li, which enter recesses cut upon the periphery ot' a disk, b2, secured t-o the axle i), when said pulley is to be putin motion or pushed inward.

Bl is a handle or shipper, hung upon a pin, having its ends 'entering apertures in a bar, b,.secured to one of the rear supports of frame A A, and passing up through an opening in said barila to a point a little above the top, of the said frame.

A swivel or button, b4, is attached to frame A, for holding the handle B? in the position shown in tig. 3,

or when it is'held so as to throw theqmlley B1 in motion.

C is a belt, communicating motion from the pulley Bl to the pulley D, located and secured'npon the projecting end of the agitator bar d of the trough D1, which trough is designed to receive grain that is to be sown in rows.

The agitatorbar (Z is furnished with distributors dl dl, for agitating the grain so as to cause it to enter the hole in the trough Dl, from which it is conveyed through a cylindrical spout, D2, attached by suitable means to the bottom Of-said trough, to the furrow in which it is designed to 'plant the seed or grain. yThe opening in seed-trough ,D1 is provided with a slide or cut-oii, di, by means of which -itmay be closed when desired. f

Dl is the grain-trough, which is suspended and made vertically movable by means ot' the screw-bolts d d, which pass up through openingsv in the top pieces or beams of the frame A A and nuts, the lower hooked ends of which4 bolts cnt-er staples or eyes fastened to the said trough. f

E designates another trough, in which it is designed to place and to be sown or deposited in hills, such as cotton-seed and the like.

This' trough is 'secured upon the front part of trame A A, by any suitable means, and is furnished with a comb-like device, e, one end of which is pivoted to its bottom, and the other end connected by a rod or bar to a spring, c', secured to frame A A. 'lhe object of the device e is to separate the seed where they adhere to each other, as is the case with cottonseed, by means of its teeth and the vibration it 1e' ceives ii'om the spring c', and thus allow the seed' to enter the .seed opening in said trough, and be carried off through its spout 1P to the furrow to receive them.

El designates a bar, pivoted at one end to the frame A A, directly beneath the trough E, and connected at its opposite end by means of a cord to one end oi' the spring c'-,

F is adisk or wheel, with a project-ion, F2, constructcd thereon, which comes in contact with the bar E2, causing'it to vibrate, which will let the seed escape from the trough E.

The cam or disk l is secured to an axle which is journaled to the frame A A, and supplied with a pulley, li, around which passes an endless belt or chain, f, passing around the pulley B, from which latter pulley said beit receives motion, communicating it to the former pulley, which in turn' operates the cam F. l

The pulley I, inits construction, consists of .a combination oi' grooved disks, the diameters of no one of Awhich is the saine; the object of which being for the purpose of giving it any desired velocity,

thereby regulating the revolutions of the cam F, causl i-ng its projection to strike a greater or lesser number of times in a given'time, the bar 1El whicl1will,in consequence thereof, regulate thenurnber of seed which it is desired to deposit in a hill.

The projection on the disk I11 is hinged thereto at its lower end, and isv attached at its oppositeend by means of a spiral spring, f,to said disk, which spring is secured within a recess or. cavity cut in said disk,

as shown ng. 2.Y Y The object of this spring is to allow the projection on the diskF to yieldA or. be pushed inward 'within the recess ot' disk- Foutof the Way', should the planterl by accident, whenfin operation, Abe backed or reversed. The front lrollers B B3 are se'cured upon an. axle, 'having its'bearings in the pendent ends o f a brace, B4, which revolves. in the desired direction when the machine is turned either to the'right 'or left hand, upon a king-bolt, g, passing through and -held in a transverse brace of frame A A. Having'thus described my invention.

What I claim -and desire to secure by Letters Patv trough E, all arranged and operating substantially as and for the purpose set forth.

In testimony thatI claim the foregoing I lhereunto sign my name this day of' January, 1871, in presence of two subscribing witnesses. v
